MACHINE FOR CUTTING-'AND BENDING LINK-BLANKS.

SPECIFICATION forming part of Letters Patent No. 357,172, dated February 8, 1887.

.Application filed May 7,'1886. Serial No. 201,471. (No model.)

To aZZ `whom it Vmay concern,.-

Be it known that I, HENRY BRUCHLER, a

citizen ofthe United States, residing at Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements inv Machines for Cutting and Bending Links; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters, or iguresof reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side elevation. Fig. 2 is a plan view. Fig. 3 is a vertical transverse section.

F, fulcrumed to the standard G, works.

My invention relates to machines for cutting and bending links for making chains; and it consists in the construction and novel combination of parts, as hereinafter described, and pointed out in the claims.

' Referring by letter to the accompanying drawings, A designates the bed-plate, which is provided with vertical side walls, B C, each of which is providedvon its inner face with a half-block, one being marked D and the other D. These half-blocksD and D have a space, E, between them, in which the bendinglever This lever is operated by hand or by a foot-treadle, as may be desired. 'lf-he half-blocks D and D', are provided in their inner faces with vertical middle grooves, H and I, the upper portions of said grooves H l. being inclined outwardly and upwardly, so that the metal' from which the link is to be formed may be bentgradually and easily. y

Tothe outside of one of the vertical side walls, B, is pivoted or fulcrumed the knife M, by which the rod from which the links are to be formed'is cut off in proper lengths as the rod is fed to the machine, the end of the rod abutting against a stop, N, at the other side ofthe machine, opposite the feeding-point.v By thismachine links may be cut Aand bent rapidly, it only being necessary to yjoin and close the open endsV of the links to form a chain after the blanks have been severed from the rod. Vertically-slotted guides X Y extend above the grooves in'the half-blocks D vated position after the lever hasbeen depressed to form the bend in the link-blank. The bending-lever works between the vertical arms of a slotted guide, W, which is closed at the top and limits the upward movement of said lever.

The operation is as follows: The stock is fed through the slotted guide X, when the cutter is raised, until the same engages the stop N on the opposite side of the frame. The

knife is then brought down by the operator,

severing the desired piece from the main wire. The lever F is then depressed upon the wire lying over the grooves in the blocks D and D', so that the same will be carried down in the `said grooves on opposite sides of the lever in loop form. The link being thus form'ed,when the lever F is raised the said link will drop out from the bottom'of the slot.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, with the bed-plate having the vertical side walls, ofthe blocks with a space between them and having the middle grooves in their inner faces, the bending-lever, and the pivoted knife or shearing-lever, substantially as specified. v

2. rIhe combination, with the bed-plate having the side wallswiththe grooved blocks on their vertical inner faces, of the bending-1ever, its controlling-spring, the weighted shearing-lever, and the slotted feed-guides and stop,
